coivieiNEnBnnmG Ni) LUBRICATING DEVICE non vnniciinwnnnns' :p jff To all whom tmajz/ co'ncerm.

Be it known that I, ORLANDO A. FRIox, a

``citizen of the United States, residing at D'efiance, in the County 1 of- Defiance and State of Ohio, haveV invented certain new`l and useful Improvements in Combinedv Bearing and Lubricating Devices for Vehicle-l/Vheels; and)1 do declare the following to bea full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.

My invention relatesbroadly to improvements in bearings for revolubly mounting the wheels of `vehicles, -and more particularly to a specific form of such device designed to v not only revolubly support the wheel, but

to lubricate the same in lsuch a manner as to allow a predetermined amount of grease to suffice for a period twice as long as such an amount would usually last. V

The object of the invention is to accomplish the above result in the most simple and v efiective manner. Inb carrying out this object, I employ the specific details of con-.

struction hereinafter described and olaimed and shown in the drawings wherein:

Figure 1 is a vertical longitudinal section through the hub of a wheel, the boxing thereof, and the sleeve to be described, this view showing a portion of an axle and its spindle in elevation, and Figs. v2 and 3 are vertical transverse sections as seen respectively on the lines 2-2 and 3-3 of Fig. 1.

In these drawings, a metal axle 1 is shown having a spindle 2 on its outer end, the

inner end of said spindle being provided with a collar 3 integrally joined thereto and to the axle 1, while its outer end is provided with a nut 4 as is common with devices of this character. On opposite sides of the i collar 3, comparatively large fillets are preferably employed, although this detail constitutes no partof the present invention.

Surrounding the spindle 2 and spaced therefrom, is a suhstantially cylindrical hub boxing 5 which is of common construction and is rotatably mounted in the hub, said boxing being of a length substantially equal to the distance between'the collar 8 and the V .nut 4.

Surrounding the spindle and contacting therewith andl withthe inner side of the boxing 5, is a bearing sleeve 7 which is of a length substantially equal to the length of said boxing, the inner end of said sleeve Specificaton of Letters Pat'ent. i i

Patnfea Juiy 6,191511* Applicationfiled.l'anuaryl1915;V SerialNo. 1,609. i i i T beingshaped to closely :engage the adj'acent i fill'et. `Aslshown, this sleeve. 7 is of greater thickness anddiameter' at its inner end than at its outei*` end, although'this detail' ne'ed not be followed too c'losely, the outer side of said sleeveis provided with -a circumferential groove 8, and the inner side therea of is provided with a similar circumfer'ential groove 9; Both of'these grooves extend inl width in opposite directions from the centerj 11' of the sleeve, as most clearly seen in `Fig.,1,`

9 has been exhausted. This amount of grease willv lubricate the spindlelal length of time equal to the usual lubricating' means,

but, when it no longer lubricates the contacting surfaces of the sleeve 7 and the spindle 2, said sleeve will tend to bind on or stick to the spindle 2,' and the boxing 5 will rotate upon said sleeve, since the coni 90 tacting surfaces of this sleeve and the boxing are lubricated by the grease-of the outer V This isv very important, since as long as the contacto I i ltically all of the grease within the groove i groove Swhich has notbeen heretofore in use. This amountv of grease will now serve to lubricate the device for a'second period i of time equal to the length of `the period which the grease inithemgroove 9 has lasted. It will therefore be seen that by constructing and arrangingb the'pa-rts as above set forth, more efficiency is gained than can be gained from any of the patents above disclosed. It' is therefore thought that although the iinprovements which I have made are only -details of construction, that' these details are suflici'ent to evidence the existence of `invention.

I c'laiin The combination with `a cylindrical spin- V dle havingv a stop collar on one end, a nut on its other end, and a cylindrical hub boxing surrounding said. spindle and spaced iic therefrom,` said boxing being of a length substantially equal to the distance between (ITK said sleeve likewise having a circumferential grease receiving groove, the latter being of a Width substantially equal to that of the other groove, Whereby to lubricate the spindle and the boxing equally under normal conditions. l

In testimony Whereof I have hereunto set my hand in presence of two subscribing Witnesses.
